Specification of Letters Patent.

Patented July 9, 1907.

Application filed September 6, 1906. Serial No. 333,437.

To all 'whom it may concern:

Be it known that I, Jnssn W. RENO, a citizen of the United States ofAmerica, and resident of the city, county, and State of New York, haveinvented certain new and useful Improvements in Inclined Elevators, ofwhich the following is a specification.

My invention relates to inclined elevators for use in department storesand the like in combination with an l ordinary stairway, where truckscontaining goods have to be transported from one floor to another,accompanied by an attendant, along the stairway.

The object of my invention is to provide an elevator of this class whichshall be simple and effective in its construction and operation andwhich may be readily installed upon an existing stairway withoutrequiring more space than that usually occupied by the stairway, andwhich shall combine an elevating means for freight or merchandise truckswith an inclined passage or stairway so that an attendant may accompanygoods left in his charge while they are being transported by theelevator.

My invention consists in the novel construction and arrangementhereinafter illustrated and described.

In the drawings accompanying and forming a pai't of this specification,Figure l is the side view, partially in section, of one embodiment of myinvention; Fig. 2 is a partial front view of the same, Fig. 3 is anenlarged sectional view on lines 3 3 of Fig. l, Fig. 4 is a partialsection on lines 4 4 of Fig. l; and Fig. 5 is a partial plan view of theparts shown in Fig. 4.

The reference characters are used in the same sense in the drawings andspecification.

Numeral l represents a stairway of ordinary construction, connecting thelower landing 2 to the upper landing 3. At the sides of this stairwayand parallel to the general direction thereof7 are arranged the inclinedguide rails 4, preferably made of channel bars. These are supported byuprights 5, or in any other suitable manner. At the lower landing a pairof sprocket wheels 6 are arranged in the plane of the guide .rails i andadapted to receive the endless chains 7, and similar sprocket wheels 8are arranged at the upper ends of the guide rails. The endless chains 7pass around the sprocket wheels ti and 8 over the guide rails 4 andreturn they are moved outwardly to their engaging positions, they willbe engaged by the lugs ll as a truck is moved along a landing toward thestairway, and at such height thatafter engagement has been made thetruck will be lifted free and clear above the steps of the stairway asit is conveyed along by the movement of the chains. In the drawings thechain is supposed to move in the direction indicated bythe arrow 15,'that is the direction in which the chain moves when the' trucks arebeing lifted from the lower to the higher floor. When it is desired totake the trucks from the higher to the lower floor, the direction of thechain is reversed, as will be obvious.

It will be observed that my invention may be easily applied to existingstairways, with small and comparatively inexpensive alterations and thatsubstantially no additional space is required for its installation.

It is one of the essential features of an elevator of this class that anattendant should be able to accompany the truck while it is being takenfrom one elevation to another. It is the practice in department storesto hold the employees responsible for goods given to their charge fordeivery and this can only be done where the employee is permitted toaccompany the goods at all times alter they have come into his charge.

Having thus described my invention, what I claim is:

l. In an inclined elevator the combination with a stationary inclinedpassageway, o1' stationary guides a1'- ranged at the sides of and atsubstantial distance above said passageway, endless chains travelingthereon, guide sheaves arranged at the upper and lower terminals ot'said guides, a drivingl shaft extendingacross and beneath saidpassageway and beneath said upper guide sheaves and means secured tosaid shaft adapted to actuate said chains.

L. [n an inclined elevator the combination with anv inclinedp.issage\\'ay and stationary guides arranged at the vsides of saidpassage-way, ot' endless chains adapted to travel upon said guides andreceptacles for goods having engaging means arranged at such height thattheir engagement with said chains will cause said receptacles to belifted bodily above said passage-way while they are beingl carried bysaid chains.

3. 'lhe combination with a stairway and inclined guides arranged at thesides and above said stairway, of endless chains arranged to travel uponsaid guides and trucks provided with engaging means adapted to engagesaid chains.

l. ln an inclined elevator the combination with a stairway andstationary rails at the sides of said stairwz'iy. of endless chainsadapted to travel upon said rails and trucks having engaging meansarranged at such height that their engagement with said chains willcause the trucks to be lifted bodily above the stairway while they arebeing carried by said chains.

5. 'lhe combination with a truck provided with engaging means and thestairway, of endless chains arranged to travel at Vthe sides and at suchdistance above said stairway to carry said trucks clear of the stairway.

(i. The combination with a stairway and its landings and trucks providedwith engaging means, of guides at the side of said stairway adapted tocarry endless chains or belts, endless chains or belts adapted to travelupon said guides, said guides being arranged at such a height inrelation to the height of the engaging means upon the truck as to causethe engagement and disengagement of the chains and truck at the landingsand te lift the trucks above the stairway at points between thelandings.

7. The combination with a stairway7 side guides and endless chainstraveling thereon, of guide sheaves or sprockets arranged at the upperand lower terminals ot` said side guides and a pair of driving sprocketsadapted to engage said chains respectively mounted on a shaft extendingacross and beneath the upper terminal of said stairway.

8. -In an inclined elevator the combination with a stairway and sideguides, of endless chains adapted to travel along said side guides,trucks adapted to travel between said side guides having engaging meansprojecting beyond the sides of said trucks and adapted to engage saidchains.

D. In an inclined elevator the combination of a stairway, side guidesand endless chains arranged to travel upon said side guides, of trucksadapted to travel between said side guides, engaging means upon saidtrucks for engaging said chains and means for throwing said engagingmeans into and out of operative position.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing Witnesses.
